Strainer separators; feeding.-In a centrifugal separator with a rotating screw-shaped spiral and a rotating filter basket particularly for the treatment of sugar, grain, coal, or water sewage, the material is fed into the machine through a hollow central axis, and the spiral and basket are rotated differentially from one driving point. End discs carried by the spindle are connected by threaded stay rods to which are secured the blades of the spiral. The boss of one of the discs is extended to form a driving pulley, and this is connected to the basket through toothed and worm gearing. The end discs of the basket are connected by bars, which have flanges to form seatings for segmental frames which hold the filtering material in position. This material does not extend to the end of the casing in order to provide a free passage for the separated material. At the forward end of the hollow central axis is a hopper with a feed screw at the bottom. The axis is cut away to form a feed opening and has a sliding gate operated by a. pinion to vary the point of entry. Pipes within the axis are connected to pipes outside the spindle but within the basket. One of the lastmentioned pipes forms a water spray to wash the material, the water then passing through the basket and the outlet; the other of the last-mentioned pipes supplies an air blast to dry the material which then passes through outlet into suitable receptacles.
